[Chijoku An] Rangyaku no Aizou ~Toshishita Shounen ni Koibito o Ubaware Mizukara mo TS Kanojo ni Sareta Seinen~ [mysterymeat3]

When a young man catches the eye of a bratty youth and his domineering girlfriend, he is dragged into a humiliating encounter that strips away his dignity piece by piece. Forced to serve as Souma-sama and Anna-sama's obedient friend, the bewildered protagonist soon finds his body transformed—renamed Saklya and reshaped into a soft, feminized form with a tight butt that invites teasing and degradation. As the power-hungry couple revels in their new toy, the tension builds between cruel domination and the protagonist's dawning realization of what he has become.
